US. Cl. 194-97 6 Claims ABSTRACT OF THE DISCLOSURE BACKGROUND OF THEINVENTION The present invention is directed to the provision of a slugrejection mechanism for use in coin vending machines, for example,automatic coin operated parking meters of the general type illustratedby United States Letters Patent 2,897,938, 2,901,078, 2,963,136 and3,026,- 983, issued to R. W. Hamilton.

In the use of such prior art mechanisms, it was found that purchasescould be made or that time could be set on the meters by use of a ringtype washer of appropriate diameter or even the pull tab of the openermechanism of the so-called self-opening beer cans. In the case of awasher, the washer will pass through the coin handling mechanism underthe driving influence of the coin drive mechanism just like a coin ofequal diameter effecting a purchase or setting the meter to register anddispense time equal to that purchased by a coin of comparable diameter.In the case of the pull tab, the purchase can be effected or full timecorresponding to that purchased by a coin of a diameter equal to that ofthe circular portion of the pull tab will be set on the meter providedthe pull tab maintains a position to present its circular portion normalto the coin traverse path in traversing the coin handling mechanism.Otherwise the pull tab will jam the coin handling mechanism at somepoint along the normal coin traverse path jamming the vending machine orthe meter with the time pointer or indicator registering an increment ofunused time and the trouble signal flag exposed to view in the meterwindow, In either case, the user of a slug will have attained hisobjective, making a free purchase of a commodity or free parking by useof a slug. While slug rejection mechcanisms have been proposed in theprior art for vending machines and parking meters, see for exampleUnited States Letters Patent 2,326,211 to F. W. Frye et al., 2,326,673to W. Patzer et al., 2,660,283 to R. F. Broussard et al., and 3,262,540to L. D. Sollenberger et al., these mechanisms all involve complicatedand expensive constructions which must be built into the mechanisms andin certain of the structures (see Broussard et al. 2,660,283)disassembly of the mechanism is required to remove the slug.

SUMMARY OF THE INVENTION In order to thwart the use of slugs and assurethe vending machine and parking meter owners of full compensation andfreedom from high service costs in removing a 3,481,442 Patented Dec. 2,1969 detected slug, the present invention contemplates a simpleinexpensive detection lever which operates to lock the coin handlingmechanism against operation and at the same time prevents the passage ofthe slug beyond the coin insertion slot thereby preventing its entryinto the coin handling mechanism and retains the slug in the coininsertion slot where it may be grasped and readily removed (1) by thevending machine or parking meter attendant in his normal policing of theVending machine or parking meter or (2) by a subsequent user desiring touse the vending machine or parking meter.

It, therefore, is a primary object of the present invention to provide asimple inexpensive slug rejection mechanism which may either be builtinto the vending machine or parking meter initially or added to anexisting vending machine or parking meter at moderate expense.

A further important object of the present invention is to provide adetector lever for sensing the presence in the coin insertion slot of avending machine, such as a parking meter, of an open centered slug thatwill simultaneously lock the coin handling mechanism against normaloperation and retain the slug in the coin insertion slot in position tobe retrieved therefrom without the need of tools or disassembly of anyportion of the vending machine.

DESCRIPTION OF PREFERRED EMBODIMENT With continued reference to thedrawings wherein like reference numerals are employed throughout toindicate the same parts, the present invention contemplates a slugrejection mechanism 10 composed of a combination coin detector andlocking lever 11, a biasing spring 12, and an attachment screw 13(FIGURE 5) for securing lever 11 and spring 12 to a portion of thevending machine or parking meter support frame 14 adjacent the entrywayinto the coin handling means 15 carried by frame 14. While slug rejectormechanism 10 may be readily applied to any vending machine coin handlingmechanism wherein forceful insertion of a coin is employed to releasethe vending mechanism for operation, the invention is here illustratedin its application to a time vending machine of the multicoin automatictype parking meter M commercially identified as the Park-O-Meter Model Kmarketed by the Rockwell Manufacturing Company. The details of thevending or meter actuating mechanism aside from those parts which definethe entranceway into the coin handling mechanism 15 in no way affect theoperation of the slug rejection mechanism and, therefore, will bedescribed generally and reference to the aforementioned Hamilton patentsmay be had for details of the meter which may not be clear from thefollowing description.

Referring for the moment to FIGURE 1, the portion of the enclosinghousing 16 defining a radially directed coin insertion slot 17 isdisposed in close radially spaced relation to an arcuate stepped opening18 formed in the annular wall 19 of dish-shaped coin pan assembly 20fixed by screws 21 to front plate 22 of the mechanism support frame 23composed of front plate 22, rear plate 24 and spacer posts 25 (FIGURE 4)fixedly joining plates 22 and 24. Coin pan assembly 20 at the lowerclockwise end of opening 18 is formed with a thickened land 26 delimitedalong the adjacent edge of plate 22 by a wall 27 tangentially related tothe outer peripheral face 28 of wall 19 of coin pan assembly 20 and anoverhanging lip 29 and at its opposite edge by the inner face 31 of wall19. As will be apparent from an inspection of FIGURE 4, the bottom 32 ofcoin pan assembly 20 is spaced slightly from front plate 22 due to theprovision of annularly spaced rearwardly protruding lands 33 and arearwardly protruding rib 35 formed integrally with bottom 32 and land26 respectively to space bottom wall 32 from plate 22 sufficiently toaccommodate a reset lever assembly 36 carried by cam assembly C (to bepresently described) located between plates 22 and 24 and providingmounting posts 37 protruding through a suitable opening 30 (FIG- URE 3)in plate 22 and a trip lever 38 having an arm 39 formed at its upper endextending outwardly through opening 18 beyond wall 27 of land 26 andterminating in an upwardly directed hooked portion and a laterallydirected upstanding release finger 40 disposed with its outer free endprojecting forwardly through opening 41 to a point clockwise beyond theend of stepped opening 18 of coin pan assembly 20 for a purpose to bepresently pointed out. Trip lever 38 adjacent and below the inner end ofarm 39 is also provided with a forwardly directed right angularlyrelated coin contact finger 45 extending forwardly through an opening41a in wall 32 of coin pan assembly 20 and disposed inwardly from thecoin entry area of stepped opening 18 a suflicient distance, determinedby abutment of release finger 40 with the inner face 31 of wall 19 ofcoin pan assembly 20, to permit coins to be inserted freely only abouthalfway into the entry area of stepped opening 18 before contactingfinger 45 and adjacent its lower end is provided with a slot aperture 46(FIGURE 1) freely passing the shank of coin pan assembly securing screw21 threaded into land 26. Trip lever 38 is normally biased downwardly toengage shank of screw 21 and cant lever 38 clockwise around screw 21 bybiasing spring 48 connected at one end to spring connector arm 49 oftrip lever 38 and at its other end to spring anchor post screw 51 whichalso serves to fix coin discharge chute 52 in place on front plate 22beneath the arcuate coin discharge slot 53 formed in wall 19 of coin panassembly 20.

Reset lever assembly 36 is removably fixed to the mounting posts 37 ofcam assembly C by screws 47 and functions to actuate the expired flag 43and trouble flag 44 between their respective display and nondisplaypositions during the time setting traverse of the coin through coin panassembly 20 at which time the coin engages beneath the terminal lip 42of right angularly related, outwardly bent vane formed on the free endof arm 51 of lever assembly 36 and moves lever assembly 36 and camassembly C counterclockwise around the center point of coin pan assembly20 for a purpose to be hereinafter pointed out.

Land 26 in vertically spaced relation to the head of screw 21 isprovided with a horizontally directed slot 54 and a tapped aperture 55for mounting a coin deflector lever 56 having spaced downwardly benttabs 57 at its lower end fitted into slot 54, a veritcally elongatedslot 58 in its body portion spanning aperture 55, an i tumed flange 59along its outer edge terminating at its upper end below vane 37 in apair of oval-shaped ears 67 and 68 respectively directed inwardly towardthe transition wall 71 of opening 18 of wall 19. A mounting screw andcoil compression spring assembly 72 threaded into aperture 55 throughslot 58 and bearing against the body portion of lever 56 secures coindeflector lever tabs 57 in place in slot 54 with car 67 normallyabutting wall 71 of opening 18 above the normal coin entry area at theclockwise end of opening 18.

Coin handling mechanism 15 conventionally includes a rotator shaftassembly 73 comprising a shaft having a reduced diameter threaded end 74protruding forwardly freely through plate 22 and a centered opening (notshown) in the center of wall 32 of coin pan assembly 20, a pressedfitted pinion gear 75 disposed on the shaft to the rear of plate 22 andincluding a hub journalled in plate 22, cam assembly C (previouslymentioned) journalled on the shaft in end facing relation to gear 75 andbiased clockwise to its home position (see FIGURE 1) by biasing spring76 (FIGURE 3) and fixedly mounting a signal actuating arm 77, a secondcompound gear assembly 78, the time drive gear assembly, journalled onthe shaft immediately adjacent cam assembly C, and a reduced diametershaft end journalled in plate 24. The threaded end 74 of the shaft ofrotator shaft assembly 73 fixedly mounts coin rotator assembly 79comprising a gear wheel 81 provided with three equiangularly spaced coininspection openings 82 located midway between the respective adjacentends of three angularly spaced arcuate coin catch plates 83 riveted tothe back face of gear wheel 81 and provided along their radial outwardedges with coextensive right angularly related coin drive and supportflanges 84 (see FIGURE 1) extending axially toward bottom wall 32 ofcoin pan assembly 28 sufliciently to intercept arm 40 of release lever38 so long as lever 38 is not rocked sufficiently in a counterclockwisedirection to disengage arm 40 from the leading end of the coin catchplate flange 84 disposed at the clockwise end of stepped opening 18 atthe time a coin is inserted through slot 17.

Pinion gear 75 of rotator shaft assembly 73 meshes with a gear wheel 85fixed to a main spring barrel assembly 86 rotatably mounted on thewinding arbor shaft 87 (FIGURE 3) of arbor gear assembly 89 which isjournalled through winding arbor shaft 87 in plates 22 and 24. Thejournal connection to plate 22 is effected through a reduced diameterend of the winding arbor shaft 87 and the journal connection to plate 24is effected through the seating of the enlarged diameter end of thewinding arbor shaft 87 on a reduced diameter end of the hub flange of amain spring holding bushing 91 (FIGURE 2) protruding through plate 24and an annular plate 92 fixed to plate 24 by screws 93 which also fixarcuate winding stem retainer plate 94 in place with its center portionseated in annular groove 95 provided in winding stem 90 to fix itagainst axial movement relative to plate 24 and winding arbor shaft 87.

As best seen in FIGURE 3, arbor gear assembly 89 also includes windingpawl and ratchet assembly 91 and an enlarged wheel gear 96 journalled onarbor shaft 87 and in meshing engagement with the small diameter gear ofcompound gear assembly 78 the larger gear of which meshes with drivepinion gear 97 of the time take-off gear shaft assembly 98 journalledthrough its opposite shaft ends between plates 22 and 24. Time take-offgear assembly 98 includes a take-off gear 99 which is engaged by idlergear 100 carried by idler arm assembly 101 journalled on shaft 102 whichis in turn journalled in pivot screws 103 threaded into plates 22 and 24adjacent their upper edges and also mounting in conventional mannerindicator gear assembly 104 and its associated mechanism for settingtime indicator pointer 105 to indicate the purchased increment of timeon scale plate 106 during time setting rotation of rotator shaftassembly 73 and coin rotator assembly 79 under influence of main springbarrel assembly 86 in well known manner when an appropriate coin tripstrip lever 38. Pointer 104, as will be clear from FIGURES 1 and 2,cooperates with the time scale of meter dial 105 to indicate theincrement of purchased parking time which the users inserted coinpurchases.

To prevent a user from inserting a flat tool, wire or the like throughthe coin insertion slot 17 to actuate reset lever assembly 36, theillustrated meter includes a squeeze lever 106 (FIGURES 1, 2 and 3)pivotally mounted at 107 (FIGURE 3) to the inside of plate 22. The freeend of lever 106 is bent at right angles and terminates in an elongatedblocking vane 108 which slopes outwardly and upwardly as viewed inFIGURES 1 and 2 from its lower end and is normally biased by spring 109(FIGURE 3) to its home position in abutting engagement with the arcuateouter edge of stepped opening 18 above the coin entryway into coin panassembly 20 to block the passage between coin insertion slot 17 and thevane 50 of reset lever assembly 36.

Referring for the moment to FIGURES 3 and 4, it will be seen that coindetector and locking lever 11 and its biasing spring 12 are secured attheir lower ends to meter support frame 14 by screw 13 in a verticallydirected frame recess delimited at the right and below the clockwise endof stepped opening 18 by a vertically extending abutment lip 29 andextend upwardly along frame 14, and that spring 12 is disposed inoverlying relation to the main body of lever 11 with its free endengaged behind a laterally extending tab 111 formed approximately midwayalong the length of lever 11 at the right side to bias lever 11 towardthe bottom wall of the frame recess and counterclockwise to abut itsleft edge with abutment lip 29. The upper end of lever 11 is bifurcatedopposite coin insertion slot 17 to form a short leg having a laterallytapering axially convex nose portion 112 the tip of which overlies theportion of stepped opening 18 of wall 19 of coin pan assembly 20 intowhich a coin or slug inserted through coin insertion slot 17 isdelivered and a longer leg 113 extending upwardly past hook ended arm 39of trip lever 38 and transversely widened immediately above hook endedarm 39 of trip lever 38 to provide a locking shoulder 114 overlying arm39 inwardly of its hooked end. At a level opposite the lower edge of arm39 leg 113 is bent out of the plane of the body of lever 11 toward theenclosing housing 16 and it terminates above the right angular bent endof squeeze lever 106 in an inwardly bent locking lip 115 (FIGURES 1 and2). Lip 115 is spaced above the right angularly bent end portion ofsqueeze lever 106 at the side of blocking vane 108 in position tointercept an outwardly bent tab 116 (FIGURE 1) formed on the rightangularly bent end portion of squeeze lever 106 and prevent risingrnovement of squeeze lever .106 unless a solid face coin is inserted inthe meter to engage the tip of nose portion 112 and pivot lever 11clockwise around securing screw 13 against the counterclockwise biasingforce of spring 12 to shift shoulder 114 out of the path of movement oftab 116.

SLUG REJECTION OPERATION Assuming meter M is properly wound to conditionthe main spring of spring barrel assembly 86 to drive rotator shaftassembly 73 and coin rotator assembly 79 counterclockwise as seen inFIGURE 1 to traverse inserted coins from the entranceway of coinhandling means 15 through the coin pan assembly 20, levers 11, 36, 38and 106 will be disposed in their respective home positions (see FIG-URES 1 and 4) under influence respectively of spring 12, spring 76 ofcam assembly C, spring 48 and spring 109. In this normal home positionof meter M, the left body edge of lever 11 will abut lip 29, the rearbody face of lever 11 will abut the bottom wall of the frame recess,nose portion 112 of the short leg will be interposed between the innerend of coin insertion slot 17 and the coin entrance portion of coinhandling means 15, looking shoulder 114 will be disposed in slightlyspaced relation above the upper edge of arm 39 of release lever 38 inthe path of movement of the upwardly directed hook portion of arm 39,and locking lip will be disposed in upwardly spaced relation in the pathof movement of tab 116 of squeeze lever 106; trip lever 38 will bedisposed with release finger 40 abutting the inner face of wall 19 ofcoin pan assembly 20 positioning coin contact finger 45 to engage theleading edge of the entering coin or slug and the hooked end of arm 39in outwardly spaced relation to shoulder 114 of lever 11; reset leverassembly 36 and its associated cam assembly C will be positioned as seenin FIGURE 1 to dispose vane 50 and its lip 42 in overhanging relation tothe counterclockwise end of stepped opening 18; and lever 106 will bepositioned as seen in FIGURE 1 with blocking vane 108 abutting thearcuate outer edge of stepped opening 18 and interposed between coininsertion slot 17 and vane 50 of reset lever assembly 36.

Insertion of an open centered washer or the pull tab of a self-openingbeer can, will result in rejection of the slug leaving the slug with itstrailing end portion projecting outwardly from coin insertion slot 17 aswill now be pointed out. The entering edge of an inserted slug will passfrom the inner end of coin insertion slot 17 into the entry portion ofarcuate slot 18 to engage nose portion 112 of lever 11 as it passes fromslot 17 to slot 18 forcing lever 11 to swing clockwise (see FIGURE 4)around securing screw 13 and pass the leading ring portion of the sluginto engagement with finger 45 of trip lever 38. Upon engagement withfinger 45 the open center area of the slug will have reached a positionopposite nose portion 112 freeing lever 11 to swing counterclockwisearound securing screw 13 under the biasing influence of spring 12 to itshome position with shoulder 114 overlying arm 39 of trip lever 38 inposition to intercept the hook end of arm 39 and locking lip 115positioned to intercept the tab 116 of squeeze lever 106. Uponapplication of further inward force upon the slug to overcome the springbias force on trip lever 38 and swing trip lever counterclockwise torelease coin rotator assembly 79 for counterclockwise driving movement,the open center of the slug will remain opposite nose portion 112 oflever 11, the hooked end of arm 39 of trip lever 38 will abut shoulder114 of lever 11 and tab 116 of squeeze lever 106 will abut locking lip115 thus preventing coin registering movement of coin rotator assembly79 and movement of blocking vane 108 from its blocking position betweencoin insertion slot 17 and vane 50 of reset lever assembly 36. As aconsequence, the coin handling mechanism 15 will be effectively lockedagainst operative movement with the slug still exposed at the outer endof coin insert slot 17 and the slug cannot enter the coin rotatorassembly 79 to elfect normal vending operation of the coin handlingmechanism 15, in this case the purchase of parking time dispensed byparking meter M.

It will be appreciated from the foregoing description that the simpleslug rejector lever 11 with its biasing spring 12 may be interposedbetween the coin insertion slot and coin handling mechanism 15 of anytype of vending machine where a traversing coin is ememployed to effecta vending operation to prevent entry of a slug into the coin handlingmechanism and retain the slug in positon for ready removal from the coininsertion slot. The present invention, therefore, provides aninexpensive slug rejection means that may be readily installed inexisting coin vending machines to prevent operation of the vendingmachine by open centered slugs and at the same time prevent jamming ofthe vending machine.

The invention may be embodied in other specific forms without departingfrom the spirit or essential characteristics thereof.
